We are developing a product that will use Asset Tracker 2 and Nordic's nRF Cloud.
We want to take advantage of the power saving offered by the LTE eDRX and PSM modes. We are trying to sort out how Asset Tracker 2 sets either eDRX or PSM timer settings, and what the relationship is between those settings and the 'activeWaitTime' that is part of the device's configuration.
So, specifically, our question is:
- Does Asset Tracker 2 use a default eDRX or PSM setting? Which one? What are the timer settings?
- How can those settings be changed?
- What, if any, is the relationship between whatever either the eDRX or the PSM settings are and the 'activeWaitTime' time setting that is part of the device configuration?
- How can we determine which setting, either eDRX or PSM that the device is currently set to? For example, if I use the AT+CPMS? command the response is: +CPSMS: 1,,,"11000001","00001010", indicating the PSM mode is enabled, and if I use the AT+CEDRXRDP command I get the response +CEDRXRDP: 4,"0001","0001","0001" which indicates the eDRX is enabled. But they can't both be on at the same time on the same device. So how do I know if eDRX is currently being used on the device or PSM?
Thanks in advance for your help!
